Both the technological
advances and the continuous dropping of prices resulted in the
desktop videoconferencing systems accessible to the wide range
of community. A stable objective governing the development of
such systems has been to increase the extent to which this distance
communication resembles the face-to-face communication.
Namely, it
would be desirable if the videoconferencing systems, while transmitting
the sound and picture, also succeed in transmitting the majority
of the non-verbal communication signs that have importance in
the human communication. For instance, these non-verbal signs
comprise the facial expression, eye-fixation, body parts movements,
posture, and outlook. Unfortunately, the previous reports show
that the videoconferencing systems do not transmit the non-verbal
signs to the extent necessary to satisfactory substitute a face-to-face
communication. One of the major factors identified for causing
the poor transmission of the non-verbal signs is the picture quality
per se. This research project investigates the effect of the frame
rate factor on the communication effectiveness in the desktop
videoconferencing systems, as well as the different aspects of
users' satisfaction with such systems. Additionally, the project
identifies preferences in using the desktop videoconferencing
systems with respect to the different types of tasks. Taking into
account the obtained results, the authors offer some recommendations
in using the desktop videoconferencing systems.
